Apparently Batista is taking time off after Extreme Rules, leaving a spot available in the stable. With Evolution being about the past, present and future, bringing in a young guy makes sense. I think it will be Cody Rhodes. It's about time he got a proper push and they are already teasing the split from Goldust. His look is perfect for Evolution too. If they want someone from NXT, Mason Ryan would be the best choice imo.
